Thieves forced their way into an antiquities museum in southern Greece on Friday, making off with 60 to 70 items of "incalculable" value. Two men in ski masks reportedly used hammers and a gun to smash their way into the Archaeological Museum of Olympia during an early morning shift change and "immobilized" one of the guards. They then shattered display case and removed dozens of items, mostly small bronze and clay statues, though a full accounting of the missing items has yet to be made. The museum, which is located near and draws most of its exhibits from the site of the ancient Olympic Games, contains some of the nation's most treasured artifacts, some dating back to the origins of Greek civilization. The country's culture minister, Pavlous Geroulanos, has reportedly already tendered his resignation due to the obvious lack of security.
